Keri went to the grocery store to get some snacks. she bought 3 bags of chips at 89? each, 5 candy bars at 50? each, and one three-liter bottle of soda at $1.89. she had to pay 8% sales tax. how much money did she have to pay the cashier?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
